STATES PATENT GEORGE LUSH COLLIS, OF MUNCIE, INDIANA.

SPECIFICATION forming part of Letters Patent No. 532,030, dated January8, 1 895. Application filed April 23, 1894. Serial No. 508,650. (Nomodel.)

To all whom it may concern.-

Be it known that I, GEORGE LUSH CoLLIs, a citizen of the United States,residing at Muncie, in the county of Delaware and State of Indiana, haveinvented certain new and useful Improvements in Machines forStraightening and Setting Axles; and I do hereby declare the followingto be afull, clear, and exact description of the invention, such as willenable others skilled in the art to which it appcrtains to make and usethe same.

My invention relates to that class of devices that are used forstraightening and properly setting such as carriage, buggy and light andheavy vehicle axles, and the objects are to construct a cheap, simpleand durable device for that purpose. I attain these objects by themechanism illustrated by the accompany ing drawings, in which- Figure 1is a perspective view of my device applied to a carriage axle that hasbeen bent upward at the inner end of the spindle, with dotted linesrepresenting the spindle after it has been pressed down in its propershape. Fig. 2 is a top plan or edge view of the beam. Fig. 3 is an edgeview of a part of my invention. Fig. at is an elevation of one of theadjusting screws; and Figs. 5and 6 are detail views.

Similarletters refer tosimilar parts throughout the several views.

A is an iron beam having each end enlarged and through which a screwthreaded hole B is made,and in these holes the outer or upper ends ofthe adjusting set screws 0 C work, all as shown in Fig. l.

The connecting link or bar D is movably secured on the beam A so thatthe said bar will stand at right angles to the beam and it may he slidalong the said beam at any place desired, as the opening E in the bar issome larger than the body of the beam A. The bar D extends down farenough to admit of the axle F passing through the hole Gin the said bar,all as shown in Fig. 1.

Each of the set screws C C is provided with ahead Hon its lower end. Onthe under side of the said head is a small pivot or center point I, andthrough the said head is made two holes J J all of which is clearlyshown in Figs. 1 and 4.

K represents a removable bearin g block and is provided on its upperface with a depression M in which the point I of the screw 0 rests whenthe device is in use. The under surface of the block K is formed with asquared cutaway portion adapted to fit over the squared portion of theaxle.

L is a similar removable bearing block except that its under side isformed with a curved cutaway surface adapted to rest on the spindle.

The operationof my invention is as follows: here an axle is to be set,the machine is placed on the axle according to where the bend is to bemade, and the machine may be set underneath, at one side, or on top ofthe axle. In Fig. l, I show a spindle bent upward, and the machineapplied on the top of the axle in order to press the end of the spindledown to its proper alignment, as indicated by dotted lines in the saidfigure. In straightening and setting a crooked axle like that shown inFig. l, I first place the beam over the axle, allowing the spindle topass through the hole Gr in the bar D and stopjust beyond the crook oron the collar on the inner end of the spindle. I then place the block Kunder the inner screw and on top of the axle, and

then place the block L on top of the spindle near the bend, after whichI turn the set screws 0 0 down until they become tight. Then by placinga small rod N into or through one of the holes J in the inner screw andturning the rod as indicated by the arrow in Fig. 1, it will run theinner end of the beam up and cause the block L to press harder on thespindle than the block K does on the axle,on account of the block Lbeing so close to the bar D. In turning the screws 0 C it is onlynecessary to turn the outer one over the block L a sufficient amount tocause the beam A to stand parallel with the axle, and the screw over theblock K being turned until the spindle is pressed down to its properplace. This same operation is performed when the device is setunderneath or at one side of the axle, the bar D always being adjustedon the beam so as to cause the block L to properly bear upon or nearwhere the bend is to be madeor corrected. I always use the blocksK and Lto fit the surface of the axle or spindle, using the block L over around or oval surface and the block K on fiat surfaces.

Having thus described my invention, I claim the following and desire tosecure the same by Letters Patent:

1. In an axle straightening device, the combination with the beam, of aconnecting ba'r slidingly secured on the same and having an aperture inits end, set screws (3,0 at opposite ends of the beam and removablebearing blocks having respectively squared and curved cutaway underportions, substantially as described.

2. In an axle straightening device, the combination with the beam havingscrew threaded GEORGE LUSH COLLIS.
